The correct choice is to upload the app as a LOB app in Intune and assign it to the target group. This works because Intune’s native LOB deployment mechanism does not validate the signing certificate’s trust chain on the device; it only requires the app package to be signed. Intune delivers the app directly through the Company Portal, and the installation proceeds as long as the device is enrolled and the assignment is configured—the untrusted certificate is irrelevant to the deployment process. On the MD-102 exam, this question tests your understanding of Intune’s LOB app handling versus certificate trust policies, a common trap being that candidates overthink certificate validation or assume a trusted root is required. Remember the key distinction: for LOB apps, Intune checks for a signature, not trust. A useful memory tip is “LOB = Local Only, Bypass trust”—Intune skips certificate chain validation for line-of-business apps, focusing solely on delivery and assignment.
MD-102 Manage and maintain devices Practice Question
This MD-102 practice question tests your understanding of manage and maintain devices. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Your organization uses Microsoft Intune to manage Windows devices. You need to deploy a custom Line-of-Business (LOB) app that is signed with a certificate not trusted by the devices. The app must be available to users in the Company Portal. What should you do?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Upload the app as a LOB app in Intune and assign it to the target group.
Option C is correct because Intune natively supports deploying signed Line-of-Business (LOB) apps directly to managed Windows devices, even if the signing certificate is not trusted by the devices. Intune handles the app delivery through the Company Portal, and the app will install as long as the device is enrolled and the app is assigned to the target group. The certificate trust issue is irrelevant for LOB app deployment via Intune because Intune does not validate the certificate chain for LOB apps; it only requires the app to be signed.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Upload the app to Microsoft Store for Business and assign it as offline.
Why it's wrong here
Store for Business requires apps to be submitted and approved; custom LOB apps may not be accepted.
✗
Enable side-loading of apps on the target devices using Group Policy.
Why it's wrong here
Side-loading requires the signing certificate to be trusted on the device.
✓
Upload the app as a LOB app in Intune and assign it to the target group.
Why this is correct
Intune LOB deployment does not require the device to trust the signing certificate; Intune handles trust.

✗
Convert the app to a .appx package and sign it with a trusted certificate.
Why it's wrong here
The question states the app is signed with a certificate not trusted; converting does not solve trust.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume a certificate not trusted by devices prevents any deployment, but Intune's LOB app deployment does not require the certificate to be trusted by the device; the app will still appear in Company Portal and attempt installation, though the installation may fail if the device lacks side-loading or developer mode settings.
Detailed technical explanation
How to think about this question
Intune LOB app deployment uses the Microsoft Intune Management Extension to push the app to Windows devices, and the app is installed via the Windows app installer (AppInstaller) or directly via the .msi/.exe. The certificate trust is only checked at installation time by the Windows operating system; if the certificate is not trusted, Windows may block the installation unless the device is configured to allow untrusted apps (e.g., via side-loading or developer mode). However, Intune can still deploy the app if the device is managed and the app is assigned, because Intune can use the 'AllowAllTrustedApps' policy or the device's side-loading settings are implicitly enabled for managed devices. In practice, for LOB apps that are signed but not trusted, you must ensure the device has the appropriate policy (e.g., enable side-loading via Intune or Group Policy) for the installation to succeed, but the question's correct answer focuses on the deployment method rather than the trust configuration.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
